Controversial some might say, but the singer’s second album has this month not only overtaken the 1973 prog classic in the UK’s all-time biggest selling albums chart, but has also overcome the next in-line, Brothers in Arms by Dire Straits, just one week later.

Martin Talbot, managing director of the Official Charts Company, commented: “It has been an extraordinary 12 months or so for Adele, and it looks set to become even more extraordinary as the days and weeks go by.”

However, Adele has some way to go before 21 becomes the biggest-selling album of all time in the UK.

It is thought that one in six British households now owns a copy of Adele’s award-winning 21, and it still remains in the charts, currently staying afloat at number five in the UK albums chart, down from number three last week.

Who is still yet to buy 21? It is hard to believe that after 61 weeks thousands of people are still purchasing the album who didn’t own it before.
